Microwave assisted extraction of mangiferin from Curcuma amada

Abstract

Mangiferin present in Curcuma amada was extracted with the help of microwave assisted extraction (MAE). The extraction solvent used was ethanol, which is eco-friendly and reduced the risk of environmental hazard. The mangiferin content was found to increase until 500 W, but decreased as the microwave power was increased further. A similar threshold was also obtained for microwave irradiation time. Following a mathematical analysis, an optimal mangiferin yield of 41 μg/mL was obtained from an extraction time of 15.32 s for a microwave power of 500 W.

Food waste: a potential bioresource for extraction of nutraceuticals and bioactive compounds

“…The main advantage of MAE over ultrasonic assisted extraction and Soxhlet extraction is that, it can be used to extract plant metabolites at a shorter time interval (Afoakwah et al 2012). Padmapriya et al (2012) extracted mangiferin present in Curcuma amada with the help of MAE using ethanol as a solvent. The mangiferin content was reportedly increased until 500 W, but decreased as the microwave power was increased further.…”

EVALUATION OF EMERGING METHODS ON THE POLYPHENOL CONTENT, ANTIOXIDANT CAPACITY AND QUALITATIVE PRESENCE OF ACETOGENINS IN SOURSOP PULP (Annona muricata L.)

“…Microwave extraction was conducted with 10 g of sample wich were placed in an Erlenmeyer flask containing 100 mL of each solvent. The flask was placed in the chamber of a microwave oven (SAMSUNG model MW830WA, Selagnor, Malaysia) operating at 600 W. The extraction was made with irradiation cycles of 10 s for 1 min (PADMAPRIYA et al, 2012). All extractions were performed in triplicate and extracts were filtered and concentrated on a rotary evaporator (Yamato, model RE300, Japan) at a temperature of 30-50 °C at 90 rpm.…”

The potential role of mangiferin in cancer treatment through its immunomodulatory, anti‐angiogenic, apoptopic, and gene regulatory effects

“…Microwave‐assisted extraction, which is known as a more environmental‐friendly process with economic advantages than the current extraction methods, has been used for the extraction of biologically active compounds from different materials. Zou et al , obtained 36.10 ± 0.72 mg/g yield of MF from M. indica leaves under this experimental conditions: 45% ethanol, liquid‐to‐solid ratio of 30:1 (mL/g), and extraction time of 123 Sec under microwave irradiation of 474 W. Padmapriya et al reported high MF yield (41 μg/mL) using microwave assisted extraction from Curcuma amada under experimental conditions, such as ethanol, extraction time of 15.32 s, under microwave irradiation of 500 W.…”
